The Decline Great Period is like "the early autumn in the four seasons," a stage where energy transitions from prosperity to decline. It is most suitable to experience during the youth growth period (20-30 years old) or the elderly retirement period (after 60 years old). There is no absolute "latest age" for the Great Period, usually extending up to around 80 years old. In the later years, the Great Period mainly affects health and mindset, like "the warm or cold of sunset depends on self-adjustment."

Which Age Is Most Suitable for the Decline Great Period
The Decline Great Period is a "transition phase of energy reduction" among the Twelve Great Periods of Longevity, similar to "the fruit beginning to shrink after maturing." It is characterized by reduced vitality and easy resistance, making it suitable to experience during life stages with strong "risk resistance" or "simple needs," like "repotting a plant, choosing young seedlings or old trees for better survival."1. Youth Growth Period (20-30 Years Old): Strong Stress Resistance and Easy Recovery
Experiencing the Decline Period in youth is like "seedlings facing storms," which may have setbacks but strong recovery power. At this stage, life is not yet set, and the resistance in the Decline Period (such as job hunting difficulties or academic bottlenecks) can actually promote reflection, like "a young tree bent by the wind grows deeper roots."
Young people have abundant energy and low cost of mistakes, so they can use the Decline Period to consolidate skills and correct directions. For example, new employees facing setbacks may clarify their goals more clearly, and students may adjust their methods due to fluctuating grades. As long as they do not blindly fight, the Decline Period can become a "grindstone for growth."
2. Elderly Retirement Period (After 60 Years Old): Simple Needs Have Less Impact
Experiencing the Decline Period in old age is like "an old tree facing autumn chill," where the pace of life has already slowed down, and the demand for career and wealth has decreased. The impact of the Decline Period is mostly reflected in reduced energy, rather than major losses.
At this stage, one can follow the "reduction" characteristic, reduce social engagements, and focus on health and wellness, like "harvesting fruits and drying them for storage," turning the Decline Period into a "opportunity for a slow life." Compared to middle age, the elderly have a calmer mindset, making it easier to accept changes like "not being able to do everything," reducing anxiety and bringing stability.
3. Middle-Age Sprint Period (40-50 Years Old): Need to Be Cautious
Experiencing the Decline Period in middle age is like "a vigorous person entering a fatigue phase," with pressure from both family and work combined with energy reduction, leading to a sense of being overwhelmed. Career-wise, there may be bottlenecks (such as stalled promotions or project setbacks), and at home, conflicts may arise from trivial matters, like "a carriage slowing down while traveling."
At this time, one should "maintain" rather than "attack," adjusting the rhythm during the Decline Period (such as reducing overtime work and cultivating assistants), using experience to compensate for lack of energy, like "an experienced coach driving slowly, stability is more important than speed."
How Late Can the Great Period Go?
The Great Period is a "phase division of life's fortune," like "the four seasons in a year," and its calculation extends naturally with lifespan, but its influence varies with age. Later-life Great Periods focus more on health and mindset, with no absolute "cut-off age," but usually extend up to around 80 years old, after which the influence of the Great Period weakens.1. Rules for Calculating the Great Period: Extend Naturally with Lifespan
The Great Period follows the principle of "men with yang and women with yin moving forward, and men with yin and women with yang moving backward," starting from birth and progressing every 10 years. Theoretically, it can extend to the end of life.
For example, an 80-year-old person who started the Great Period early (at 1 year old) can have up to 8 steps of Great Period (up to 80 years old); someone who started late (at 10 years old) can have up to 7 steps (from 70 to 80 years old). Like "turning calendar pages, you count to the page you live on," the calculation of the Great Period does not set a "latest limit," but must be judged based on actual lifespan.
2. Characteristics of Later-Life Great Periods: Influence Decreases with Needs
After 60 years old, entering the later-life Great Period is like "the four seasons entering winter," where the influence of fortune shifts from "career and wealth" to "health and mindset."
At this stage, the resistance from the Decline Period and Illness Period mainly manifests in reduced energy and less social interaction, rather than major gains or losses, like "a fire gradually weakening, warmth is enough without strong flames." For most people, the "good or bad" of the Great Period after 80 years old has little impact on life's core, focusing more on "accepting natural aging," without overthinking the good or bad fortune.
3. Practical Significance: The Latest Age of the Great Period Should Not Exceed Life Expectancy
From a practical perspective, the latest age of the Great Period is generally around the expected lifespan. For example, with an average life expectancy of 70-80 years, the Great Period usually extends up to around 80 years old.
Beyond this age, the practical significance of fortune analysis decreases, like "repairing an old house, the focus is on keeping warm rather than renovating." If the elderly are physically healthy, attention can be paid to "light health care" and "family harmony"; if health is poor, focus should be on "reducing disturbances" and "keeping a calm mind."

Q: Should someone in middle age leave their job to rest during the Decline Period?
A: No need to resign hastily; it is better to "change positions without leaving, reduce responsibilities without decreasing efficiency." For example, moving from a high-pressure management position to a consulting role, using experience to shine rather than relying on physical strength, like "an old cart changing to carry lighter cargo." If a change is necessary, first save 3-6 months of living expenses, and use the "reduction" characteristic of the Decline Period for career planning, avoiding impulsive decisions.
Q: Does a bad Great Period after 80 years old still have an impact?
A: The impact is very small, and the focus should be on "adjusting one's mindset." The Decline Period and Illness Period in old age are more about the natural aging of the body, like "the sunset getting darker naturally," which can be improved through regular sleep patterns and family companionship. There is no need to worry about the good or bad fortune, maintaining a "smooth and accepting fate" mindset is more important, like "even though the branches of an old tree are dry, birds still come to rest on them."
